Birthday Collage Portrait With Face Match

Create a stylish, vertically oriented (3:4) premium birthday digital collage using the uploaded reference photo, with STRICT facial identity preservation. Face-match enforcement (very important): the generated face must be 100% identical to the reference image. Use the reference image as the only facial source. Do not alter facial structure, proportions, skin tone, or hairline. Preserve natural skin texture, pores, and real facial details. No beautification, no face morphing, no stylization of facial features. Face must remain fully visible and unobstructed. Glasses must match natural proportions and sit realistically on the face. Central Subject (Main Portrait): Young man sitting on the floor in a relaxed, confident pose. Body angled slightly to the right, face turned directly toward the camera. Left knee raised, left hand resting on it, clearly showing a silver watch with a dark dial. Right leg folded flat on the ground. Expression: bright, confident, joyful smile (birthday vibe). Appearance: natural skin, naturally styled hair, well-groomed short beard (if present in reference). Thin wire-rim aviator-style glasses. Outfit: oversized dark grey knit sweater with ribbed crew neck and cuffs; dark trousers with vertical ribbed texture (corduroy-like), black or deep charcoal; black leather Chelsea boots. Background & Collage Inserts: Background: solid dark purple matte texture in deep violet tones. Subtle purple rim-light / haze on the subject’s left side (viewer’s left). Soft floating dust/particle overlays for depth. Four smaller portrait inserts (floating cluster, NOT a grid) positioned above and to the right of the main subject: - Top Right: smiling headshot, looking upward, framed with a torn paper edge. - Middle Right: serious direct-gaze headshot, framed like a classic film negative. - Middle Left (slightly tilted): profile shot looking downward/sideways, framed inside a film strip. - Bottom Right (of cluster): smiling headshot with a glowing purple neon frame. Each insert must clearly depict the same person with perfect face match. Typography: Top-left corner text: “Happy Birthday”. Style: neon-light typography, glowing purple with white highlights, appearing as a real neon sign mounted on a dark wall. Clean, modern, premium - not cartoonish. Overall Mood: trendy, urban, sophisticated, premium birthday aesthetic. High clarity, cinematic lighting, professional poster-quality output.
